Specification of Letters Patent.

Application filed June 29. 1914. Serial N 0. 848,067.

To all whom it may concern Be it known that I, HANS mechanical engineer, subject of the German Emperor, and resident of No 239 Sohiitzenstrasse, Altona-on-the-Elbe, Germany, have invented new and useful Improvements in Adjusting Devices for Pattern-Cylinders of Printing-Machines, of which the following is a-specification.

The present invention relates to an improvement on the device for adjusting the pattern cylinders of machines for printing upon webs of paper or fabric as described in the specification of Letters Patent No. 1083543.

According to the invention a pointed mandrel is used for adjusting the pattern-cylinders, the mandrel being connected to carriages of the respective color mechanisms which are moved at the same time as the corresponding pattern-cylinders, and in the ratio of 2:1 as set, forth in the specification of Letters Patent No. 877570. The pointed mandrel is used for the purpose of bringing opposite the point of ,the mandrel certain points of the pattern-cylinders, for example the points at which the patterns begin, the so-called Picot, so that the pattern cylinders can be accurately adjusted successively both transversely and longitudinally to the pattern. In order that the pointed mandrel may be used for successively adjusting any suitable number of pattern-cylinders accurately, whatever may be the diameters of these cylinders, a small support is secured to the carriage of each color mechanism, which must be capable of adjustment'on the machine bo-th transversely and longitudinally to the web of paper or fabric to be printed upon, so that the point of the mandrel, the axis of the pattern-cylinder and the axis of the impression-cylinder are made to lie in a straight line. It is thus possible to use the device according to the American specification 877570 for adjusting the patterncylinders, as then the movement of the pointed mandrelmust accurately correspond with the movement of the color mechanism and pattern-cylinder in the ratio 2 :1 no matter what the diameter of the pattern-cylin- J ENS MEYER,v

adjustment of the point in question directly in the peripheral line, whereby the accurate ad ustment can be immediately eifected which was not the case with the previously known device. Consequently the regulator hitherto necessary for overcoming small errors could be entirely dispensed with if the die sinker would accurately bring forward the starting point of the pattern (Picot) on each cylinder.

According tothe present invention the adjustment of the central wheel or disk by a pin or mandrel is omitted for practicalreasons, and this arrangement is replaced by marks on the central wheel arranged according to the angular distance between the pattern cylinders and adjusted successively to register With a fixed mark on the frame.

In the accompanying drawing, Figure 1 shows a plan, Fig. 2- shows a side elevation and Fig. 3 shows a front elevation of the new device. Fig. 4 is a detail section taken on the line 4-4 of Fig. 1. Fig. 5 is a similar view showing a different position of the mechanism. side elevation of the mandrel and its corelated parts. Fig. 7 is a detail section taken on the line 77 of Fig. 6'. Fig. 8 is a detail section taken on the line 8-8 of Fig. 7. Fig. 9 is a detail section taken on the line 9-9 of Fig. 8. Fig. I0 is a detail section taken on the line 1010 of Fig. 1.

The periphery of the central disk 5 on the I shaft of the impression-cylinder is provided with as many marks I, II, III, IV as there are colors or pattern-cylinders e, 6 e 6*. The distance between these marks, in angular measure, corresponds to thedistance between the pattern-cylinders. The marks are on members a which are adjusted in the required angular positions upon the central disk I). On the machine frame M is rigidly secured an arm 3 of which the front end passes over the central disk 6 and carries the Fig. 6 is an enlarged detail counter-mark (stroke) X. The marks I, II, III, IV are successively adjusted to the counter-mark X. The carriages g and s for supporting and receiving the pattern-cylinders and color mechanism respectively are connected together by gearing according to the specification. of Letters Patent N 0. 877570 in such a manner that the color mechanism and the pattern-cylinder are moved at the ratio 2:1. In one of the carriages s of each color mechanism is mounted a support 6 adapted to receive the mandrel M which at its free end is provided with an adjustable bolt u having a point u The support t is adjustable on the carriage both transversely and longitudinally, and is so adjusted that the point u of the mandrel u, the axis of the pattern-cylinder and the axis of the impression-cylinders lie in a straight line, as will be clearly seen in Fig. 2. The mandrel u is inserted into one of these supports t, and is so retained therein that it cannot turn. When inserted it abuts against an adjust able pin '1: in. the base of the support.

Extending from the side of the support t, is an attaching ear t, and adjacent andbetween the said ear and the support 3, is an intermediate adjusting block 8', a screw :7 is threaded into the blocks 8 and its head end extends into a recess t the screw F, has a roller t, mounted thereon and the roller is adapted to engage a recess t, in the block t. In the same manner a screw 8 is threaded into the side of the support 8, a roller 8 is mounted on the screw, said roller operating in a recess 8*. It will be seen that if the screw t, is rotated, the support t, will be moved vertically by reason of theengagement of the screw with the block, and correspondingly if the screw 8 is turned a lateral movement will be imparted to the block 8, and the support 27, carried thereby.

For the purpose of securing longitudinal adjustment a bolt 21 is threaded into the support t, and bears against the inner end of the mandrel, as clearly illustrated in Fig. 8, a jam nut 41' serves to hold the bolt against turning. For securing a rough adjustment of the mandrel, a vertical slot is formed in the ear t, as indicated at t, and a horizontal slot is similarly formed in the carriage s, as

- indicated at s, the bolt 2?, is adapted to pass through these slots and a certain latitude of adjustment of the support t, and block 8, is thuspermitted andthey may be held by the tightening of the nut on the bolt t.

After the adjustment of the pattern cylinder has been made, it will be necessary to secure it in its adjusted position, therefore a collar 0, is provided surrounding the pattern cylinder shaft and secured at one side by a screw 0, a square headed bolt-0 serves to clamp the collar to the shaft, and as the collar is fastened to the carriage g, the shaft will be held against rotation. For the puramazes pose of accommodating various sizes of pattern cylinders, a mechanism is illustrated Worm sha t and worm 2 arejournaled in the frame and are adapted to mesh with aworm wheel 3, said wheel is mounted on a shaft 4, which is also journaled in the frame. Pinions 5 and 7 are also mounted on the shaft 4 and pinion 5 engages a rack bar 6, forming a part of carriage s, While the pinion 7 meshes with an idler 8, which is journaled in the frame, a pinion 9 engages the idler 8 and also a rack 10, which forms a part of the carriage g, a hand wheel 11 is secured to the worm shaft 2. It will thus be seen, that upon operating the hand wheel, the carriages s and 9, will be moved toward or away fro m the impression cylinder with a speed ratio of 2:1 res ectively. Various diameters of pattern cy inder may be inserted and the mandrel point it" will be .found to always be in a position to coincide with the point to, when the starting points of the pattern and impression cylinder are in contact.

When the mark I has been adjusted to the counter-mark X, the mandrel is inserted into the support If mounted in the carriage s of the, color mechanism opposite the pattern-cylinder e which is to be adjusted first. mounted in the mandrel u is directed exactly radial to the periphery of the patterncylinder e. This is now turned and moved by means of the hand lever 12 until the point w, which for example indicates the beginning of the pattern (Picot), is opposite the point 11?. When this has been done the shaft of the pattern-cylinder is locked by the coupling o. The pattern-cylinder e is now adjusted. The mandrel u is now withdrawn from the support It and inserted into the support t of the next color mechanism, while the central disk 6 is turned until its mark H The point u of the bolt .u

is opposite the mark X, and the operation as hereinbefore described is repeated. This operation is repeated for each pattern-cylinder.
